Be it known that I, JOHN Goon, a citizen of the United States, and aresident'of Far Rockaway, in the borough of Queens, in the city Thisinvention has for its object the preparation of vegetable fibers ofconsiderable length, Such as are known-as sisal hemp and ma-' nila hempand used for the manufacture'of, Such fibers have hereto-f twine'andcordage'. I I 5 fore commonly been transported tothe market or place ofmanufacture in balesfcontaining them in bunches, which are packedtogether in such comparatively loose condition as to render the balesvery bulky in proportion to their weight. By the machinery which is thesubject of the present invention the fibers are so prepared and baledthat bales of given weight are less bulky, and consequently can betransported at less expense. The bale is composed of a continuousslightly-twisted roving, which is tightly coiled into a compact body,which body is to be bound with ties or hands and may or may not beenveloped with a protecting material, as canvas. The fibers 3o baled inthis way may be made to occupy,

weight for weight, about or little more thanv half the space occupied bythe bales filled and packed in the way heretofore practiced, and,

ing in which the fibers will be self-retained inv desirable relation toeach other for transportation and at the same time forming the saidsliver into a compact coil; third, automatic regulating devices betweenthe said mechanisms whereby a proper relative speed may be form bulk orthickness, and, fourth, means for facilitating the removal of the coiledroving from the machine.

designate the framing of the machine;

.Of chains, bars, and gill-pins arranged one in advance of the other forperforming the combing, hackling, or spreading of the fibers which aresupplied to the first train from a reciproeating feed-carriage g. Thetrain a is carried by wheels it a on shafts 'k, and the train f iscarried by wheels Zm on shafts a 0, said shafts being supported inbearings on the framing a a and the lower parts of the chains of thetrains being held from sagging by idler-wheels 29', supported on theframing. The two trains are substantially like those com mon inspreading-machines and may be driven-in any suitable manner so that thesecond train f runs considerably faster than the first train a. Thetrainf is driven by its shaft 0, as will be hereinafter described, andthe train is driven from the train f by gearing between the shafts ofthe two trains in a manner well known in machinery of the kind. Thereciprocating feed carriage shown in Fig. 1 is fully described in andclaimed as part of the subject-matter of my United States LettersPatents No. 608,979 and No. 608,980 and is driven in the same manner bya connection 9 with a switch nut r on cross threaded traversescrews 8 onone side of the framing. It is not necessary to describe particularly Ithe means for driving this traverse-screw, as it may be driven in anysuitable manner from the driving-shaft 0 of the pin-trains; but it isrepresented in Fig. 1 as driven bya gear 25 on said shaft 0 through asmaller gear a and a pulleyo, which run together on a stud affixed tothe framing, said gear or engaging with and deriving motion from saidgear t and the said pulley a transmitting motion, through a belt w, to apulley on a stud wand the said pulley transmitting motion throughbevel-gears .2 to the traverse-screw.

Before describing the driving mechanism through which the driving-shaft0 of the pintrain derives motion at a properly-regulated speed fromthemain shaft 7) of the machine I will describe the mechanism fortwisting the sliver into the roving and for coiling the said roving forbaling. The principal parts of this twisting and coiling mechanism areaflier 1 and a bobbin 2. (See Figs. 1, 4, 5, 6, 7.) The flier, which isopen at one end, has at the other end a long journal 3, which runs infixed bearings 1 on the framing and is furnished with a capstan 130,which may be such as is common to the fliers of twisting-machines. Thebody or sides of this flier are represented of cylindrical form and assupported by four antifrictionrollers 5, which turn on fixed studs 15,carried by a circular frame or arch 6, erected across the framing a a.This flier is driven at a proper speed from the main shaft 7) of themachine through a spur-gear 7, fast on its journal 3. A bevel-gear 8 onsaid shaft 7) gears with and drives a larger bevel-gear 9, fast on ashaft 10, arranged in bearings outside of the framing a, and the saidshaft 10 is with and drives the spur-gear 7 on the flier.

The bobbin 2 is carried by a spindle 17 18, which is concentric with theflier. This spindle is made or divided in two lengths, which are unitedby a socket 19, formed on the outer end of the part 17, which is nearlyall contained in the flier, and receiving the inner end of the part 18,which part is of very considerable length and turns in bearings 20 on aturn-table 21, which turns on a stand 22, erected on the framing (1.. Toprovide for the turning of the two lengths or parts 17 18 of the spindletogether, the part 18 is furnished (see'Fig. 11) with a short tongue 23,which enters a slot in the end of the socket 19, said socket and tonguethus forming a coupling. The said parts 17 18 of the bobbin-spindle areeach provided with one of two portions of a longitudinal feather 24,which two portions are in line with each other when the tongue 23 is inengagement with the socket 19, so that both of said portions engage witha groove in the bore of the bobbin 2 for the purpose of turning thelatter, and the bobbin may slide lengthwise from one to the other ofsaid parts of the spindle. The part 17 of the spindle is provided at itsinner end with a long journal 2 1*, (see Fig. 11,) which is fitted toturn in a bearing 2%? in the head of the flier and also to slidelengthwise, as and for the purpose hereinafter described, in saidbearing. For the purpose of rotating the bobbin-spindle at a lowervelocity relatively to the flier, in the same direction therewith, thepart 18 is furnished with a bevel-gear 25, which derives motion from abevel-gear 26 on an upright shaft 27, arranged in the center of theturn-table 21, the said shaft having an upper bearing in the turntableand a lower bearing in a bracket 28 on the framing. This shaft 27receives rotary motion through bevel-gears 29 30 from a horizontal shaft31, working in hearings on the framing a, the said shaft 31 receivingmotion through a belt 32, running to a pulley 33 thereon from a pulley31 on a shaft 35, which runs in fixed hearings on the framing a a, thesaid belt being represented (see Fig. as also running on anidler-pulley. This shaft 35 derives motion from the main shaft I!through a belt 36, running from a pulley 37 on said shaft 1) to a pulley38 on said shaft 35.

Between the flier and the pin-train f there is arranged a conductor 39for gathering into a sliver the lap of fibers which is received fromsaid train after the hackling, spreading, or drawing operation performedby and between the pins of the two trains e f, and between the saidconductor and the flier is a nipper 40, which forms a part of theautomatic 47 to the framing.

"speed-regulating devices to be hereinafter def scribed and throughwhich the said sliver passes to the flier to be thereby twisted into theloose roving, and thereby wound'upon the bobbin to form the coil, whichafter its removal from the bobbin is to constitute the bale or the bodythereof.

The tension of the belt 32, even atits slackest, is always sufficient totransmit the small amount of power required for driving thebobbin-spindle; but the said belt also serves as a means of producingfriction on the pulley 33 for the purpose of counteractingin aproperdegree the tendency of the flier to pullthebobbin roundwithit,such counteraction preserving the requisite tension of the portion ofthe roving which is passing from the flier to the bobbin. The saidfriction requires to be increased as the diameterof the coil of rovingon the bobbin increases, and this increase I obtain by increasing thetension of the belt, and for this purpose I employ the devices which Iwill now describe with ref-1 erence to Figs. 4, 5, 7, and Aboveandbearing on the upper run of said belt 32 there is a large idler-pulley42, which turns on a.

pin 43 in an upright slide 44, which works in a fixed upright guide 45and which is carried by a lever 46, fulcrumed at one end by a pin Theother end of said lever iseonnected with a slide 48, which works in afixed vertical guide 49 on the framing. To this slide a screw 50 (seeFig. 1-0) is connected in such manner that it cannot turn, and fitted tothis screw is a nut 52, the exterior of which is'toothed to form abevel-gear,

which rests upon the head 53 of the guide 49,

the screw passing freely through said head and the nut 52 being helddown to the said head 53 by any suitable means, such means in theexample shown being the bevel-gear 54 on the short shaft 55, which runsin a fixed bearing in a bracket 56, secured to the framing a, a.

causes the turning of the nut 52 in a, direction to raise or lowerthe-screw 50, the slide 48, and the corresponding end of the lever 46,

and so to raise or lower the pulley 42 and increase or diminish itspressure on the belt 32 and the tension of the latter, so that it mayslip more or less, as required, to preserve a proper tension of theroving between the bobbin and the flier. For the purpose ofautomatically turning the shaft'55 it is furnished Witha pulley 56,which receives a belt 57 from a pulley 58 on a shaft 59, which runs infixed bearings on the main framing and which is also furnished with aworm-gear 60, through which itderives motion from an endless screw 61 onthe shaft 31, hereinbefore described. 4t the commencement of the windingof I the roving upon the bobbin, when the draft of the roving betweenthe flier and the small coil on the bobbin is least effective in pullingthe bobspeed of the flier.

the proper height.

The turning of the said shaft 55 and its bevel-gear 54 in one directionor the other bin forward with the flier and the counteracting frictionof the belt 32 is least required thescrew 50 and the slide 48, the lever46, and the pulley 42 are in the highest position and the belt isslackest; but as the winding of the roving on the bobbin proceeds'thenut 52, receiving rotary motion'from the shaft 31 through the endlessscrew 61, worm-gear 60,'pulley 58,

belt57, pulley 56*, shaft 55, and bevel--gear'54,

causes the depression of the screw 50, slide '48, lever 46, and pulley42, and so increases the tension of the driving-belt to meet therequirements, reducing at the same time-the For the purpose of limit--ing the upward movement of the screw 50 and the minimum pressure of thebeltat the commencement of winding on the bobbin an adjustablestop-collar 62 is clamped to the screw 50 below the head 53 of the guide49,.the said headconstituting a stop to stop the sc'rew'at For thepurpose of turning back the nut 52 and raising the screw 50 toits's'tarting position the shaft .55 is furnished'with a hand-wheel63,and the engagement of the pulley 56 with said shaft is made by aratchet-wheel and pawl 64, through which the said shaft is driven onlyin the direction for depressing the screw.

A"traversescrew 65, such as is commonly employed for producingthe-traverse of the bobbin within the flier in certain classes ofspinning machinery, has its journals fitted to turn in bearings 66 onthe turn-table 22. The switch-nut 67, working on-this screw, isconnected with the outer head of the bobbin by a rod 68, which isparallel with the bobbindescribed, by a small spur-gear 72 on the saidshaft, which engages with and drives alarger spurgear 73, turning on afixed stud 74, carried a'bracket 75 on-the end of the fram ing a a, thesaid gear 73 engaging with and driving a spur-gear 7 6 on thetraverse-screw.

The object of the turn-table 22, which carries the driving length 18' ofthe bobbin-spindle and most of the appurtenances of said spin:

dle and bobbin, is to facilitate the removal 3 from the machinery of afull bobbin and its replacement by an empty one, for whichpurpose theturn-table is turned, as shown in Figs. 8 and 9, to the extent of aquarter-revolution from the position represented in Figs. 1 4, 5,

6, which it occupies duringthe twisting and winding operation. Thisturning, it is obvious, cannot be done until the. bobbin is with- Idrawn entirely from the flier, and in order to 3 &

permit it to be done the length 18 of the spindle, which is ontheturn-table, and'the length 17, which remains in the flier, must beuncoupled at 19 23. To provide for this uncoupling, the journal 24* onthe length 17 of the spindle (see Figs; 6 and 11) is made long enough toslide in its bearing 24* in the flier-head far enough to permit the slotin the end of the socket 19 to engage with and be disengaged from thecoupling-tongue 23 on the length 18 of the spindle, which is so fittedto its bearing 20 on the turn-table as to be incapable of longitudinalmovement. When the spindle length 17 occupies the position of engagementshown in Fig. 7 with the length 18, it is locked in such engagement by astop-pin 7 7 which is inserted through the bearing 24 in the flier-headbehind the inner end of the journal 24; but when it is desired todisengage the two lengths of the spindle the pin 77 is withdrawn frombehind the journal and the spindle length is pushed back in the flier byhand or any suitable means far enough to uncouple the coupling 19 23.As, owing to the length of the flier, it would be difficult to withdrawand reinsert the stop-pin 77 by hand, I provide for this purpose thedevices shown in Figs. 6 and 7, wherein the stop-pin is shown attachedto one end of a lever 78, which works on a fulcrum-pin 79 on theflier-head, and the other end of which is connected by a link 80 withone arm 81 of a small rocking spindle 82, arranged in or on the interiorof the flier. The front end of this spindle 82 carries a handle 83, bywhich it may be turned to operate the stop-pin 77.

To provide for the quick removal of the full bobbin from the spindlelength 18 when the turn-table and bobbin have been turned to theposition shown in Figs. 8 and 9, 1 provide, as shown in said figures, onone side of the turn-table, at a suitable distance therefrom, astationary column 84, upon which there is fitted a rotatable head 85,from which project in opposite directions two opposite spindles 86,which are on a level with the spindle 17 18. A spare bobbin is kept onone of the said spindles 86, as shown'in Figs. 8 and 9. When the bobbinis turned aside with the turn-table to the position shown in thosefigures, the

empty spindle 86 is turned to a position in line with the spindlelength18, as shown, and the bobbin is drawn off the said spindle length andonto the said spindle 86. The two spindles 86 are turned to changeplaces and the empty bobbin is drawn lengthwise onto the spindle length18, from the spindle 86 which is opposite to it. The full bobbin is thenat a convenient time removed from the other spindle 86 to be replaced byan empty one. To provide for the easy turning of theturntable by hand,the spindle 18 and the rod 68 are prolonged beyond their bearings on theturn-table to serve as hand-levers. To look the turn-table either withthe bobbin-spindle member 18 in line with the axis of the flier or withthe said spindle member turned toward the spindle-column 84, a movablelocking-pin 131 is inserted through a hole in the turn-table and one orother of two suitably-arranged holes in the top of the stand 22.

I will now proceed to describe the driving and automaticspeed-regulating mechanism through which motion is transmitted from themain shaft]; to the driving-shaft 0 of the pintrains ata speed which isso regulated that the pin-trains supply a sliver of suflicient volume togive a roving of uniform bulk or thickness. The said shaft 0 has, asshown in Fig. 14, keyed fast upon it at one end the spur-gear t,hereinbefore mentioned, which carries a ratchet-wheel 88, and it haskeyed .fast upon it near the other end a ratchet-wheel 89. The saidshaft has also loose upon itspur-gears 90 and 91. The gear 90 carries apawl 92, engaging with the ratchet-wheel 88. The gear 91 carries a pawl93,which engages with the ratchetwheel 89. The gears 90 91 gear, res1'ectively,

with pinions 94 95, which are carried by gears 96 97, running on twostuds 98 99, afiixed to opposite sides of the framing (1 These gears 9697 gear, respectively, with pinions 100 101, which are each carried byone of two shafts 102 103, which are arranged in line with each other,as shown in Figs. 2, 3, and 13, in bearings on the framing a a. Theshaft 102 has fast upon it a pulley 104, which receives a driving-belt105 from a pulley 106, fast on the main shaft 6, and the said shaft 103has loose upon it a pulley 107, smaller than 104, which is coupled withand uncoupled from it, as hereinafter described. This pulley 107receives a driving-belt 108 from a pulley 109., larger than 106, fast onthe main shaft 1). The belts 105 and 108 respectively drive the pulleys104 107, which drive the shafts 102103, whose pinions 100 101 drive thegears 96 97, whose pinions 94 95, respectively, drive the loose gears 9091 on the pin-train driving-shaft 0. The pulley 104 thus drives the gear90 and the pulley 107 thus drives the gear 91; but 107, by reason of itsbeing smaller than 104 and of its being driven from the larger one, 109,of the two pulleys 106 109 on the main shaft drives its respective gear91 faster than the pulley 104 drives its respective gear 90; but theslower driving-pulley 104 being fast on the shaft 102 is always drivingthe gear 90, while the faster pulley 107 being loose on its shaft 103only drives when coupled therewith. The necessary coupling anduncoupling of this pulley with and from its shaft 103 is efiected underthe control of the nipper 40 through a flanged friction-hub 109 which isfitted loosely to said shaft and which for the purpose of turning saidshaft carries two laterally-projecting pins 110 110, which receivebetween them an antifriction-roller 111, carried by a pin 112, radiallyprojecting from a collar 113, which is fast on said shaft. The

passing through it.

relation between the pins 110 and the roller 111 is shown in Fig. 15,which represents a transverse section of the shaft 103 taken immediatelybehind the hub 109*. The contiguous faces of the said hub and of thepulley 107 constitute friction-surfaces through which the pulley 107 iscoupled to the hub 109? and thence through the pins 110 110 and theroller 111 with the shaft. The movement of the hub 109* toward and fromthe pulley 107 for coupling and uncoupling is effected through arockinglever, the fulcrum of which is a rock-shaft 114, arranged below and atright angles to the shafts 102 103 in fixed bearings on the framing, thesaidlever having two arms 115, which project upward, as shown in Fig.13, onopposite sides of the shaft 103 and which carryantifriction-rollers 116, which work between.

the flanges on the ends of the hub 109*, A third and longer arm 117 ofthe said lever projects upward against the edge of one armor side of anelbow-lever or bell-crank 118 which works horizontally upon a fixedfulcrum 119 in a stationary bracket 120 (see Fig. 2) on the framing, theother side or arm of said elbow-' lever or bell-crank being connected bya link 121 with the arm 122, which carries thenipper 40. This arm iscarried by a rock-shaft123, which works in fixed bearings on theframing.

A spring 124 holds the arm 117 to the elbow lever 116 and acting throughsaid lever on the nipper-carrying arm 122 tends to hold back the nipperin opposition to the drag of the sliver there is a fixed but adjustablestop 129 to restrict the forward movement of the nipper to] what isnecessary. 7 Opposite the back of the loose hub 109* there is arranged astationary but adjustable brake for arresting the movement of the shaft103 when said hub and said shaft are uncoupled from the loose pulley107.

This brake consists of a bar 125, which is held in proper endwiserelation to said hub ina stock 126, fastened to the framing a. Thisrollers 116 that the coupling-hub 109* on the I shaft 103 will be freefrom the pulley 107 and no driving of said shaft takes place, the saidpulley turning loosely on-its shaft. The traindriving shaft 0 is thendriven-by the slower gear 90, which derives motion, as hereinbeforedescribed, from the pulley 104 and transmits motion to the shaft throughthe engagement of its pawl 92 with the ratchet-wheel In front of the arm122' 88, which is permanently fastened to the shaft, as hereinbeforedescribed. As soon, however, as any perceptible diminution in the bulkof the sliver takes place and the tension of the spring prevails overthe draft of the sliver on the nipper the latter'falls back far enough,followed by the elbowlever 118, to permit said spring byf'its action onthe lever 117 116 to force thecbupling-hub 109? into frictional contactwith the pulley 107, which being driven from'the main shaft 6 throughthe pulley 109 and belt 108 and being prevented from movinglengthwise'on the shaft 103 by coming in'contact with the shaft-bearing87 (see Fig. 13) drives the said hub and the shaft 103 through suchfrictionalcontact. The pinion 101 then, as hereinbefore explained,drives the loose gear91 on the shaft 0. This gear 91 by its detachedpawl 93 drives the ratchetwheel 89, which being fast on the shaft 0drives the said shaft faster relatively to the flier than it had beendriven through the pulley 104,

gear 90, and their intermediate shafts and gearing, and so increases thesupply of fiber and the bulk of the sliver to betwisted. While the shaft0 is thus driven at the increased speed, the ratchet-wheel 88 passes bythe pawl 92, carried by the slower-moving loosegear 99. On

the other hand, while the faster-moving pulley 107 is uncoupled and theslower-moving pulley 104 is driving the teeth of the ratchet-wheel 89,which is turning with the shaft 0, pass by the pawl 93, carried by theloose gear 91, which remains stationary and is so held by the contact ofthe coupling-hub with the stationary brake-bar 125, the said hub beingpressed back against said brake-bar by the draft of the fiber in thenipper when said draft is suflicient to overcome the tension of thespring 124, and so produce, through the nipper-arm 122, bell-crank 118,and lever 117 116, the proper throwing back of the couplinghub from thepulley 107, In the operation the unavoidable tendency to sliglitvariation in the bulk of'the sliver causes the nipper to constantlyvibrate back and forth and by its action to produce constant orfrequently-repeated change of driving from the slower to the faster ofthe pulleys 104 107, and vice versa.
